在全局更改应用程序委托中的着色颜色之后，暂时更改着色颜色

My iOS app's color theme is used to set the app's global tint colors. However, in some cases this results in white text on a white background (which I would like to avoid). Is there a way that I could temporarily change my global tint color (or set a specific tint color for that instance)?

我的iOS应用程序的颜色主题是用来设置应用程序的全局色调。然而，在某些情况下，这会导致白色背景上出现白色文本(我希望避免这种情况)。是否有一种方法可以临时更改全局着色颜色(或者为该实例设置特定的着色颜色)?

The two tint colors in particular that I would like to change within the app are:

我特别想在app中改变的两种色调是:

UINavigationBar.appearance().tintColor
UIBarButtonItem.appearance(whenContainedInInstancesOf: [UINavigationBar.self]).tintColor

Specifically, I would like to change the tint color in a situation where I do not have direct access to the view (such as, when I use UIActivityViewController to share an article and the notes' dialog "cancel" and "save" buttons are white-on-white).

具体地说，我想在没有直接访问视图的情况下更改着色颜色(例如，当我使用UIActivityViewController来共享一篇文章时，notes' dialog ' cancel '和' save '按钮是白色对白色的)。

You can override the global tint colors in a specific view controller for a specific component.

您可以覆盖特定组件的特定视图控制器中的全局色调。

For example if you set the global tint color for UIButton to blueColor, you can do this in your view controller to override the tintColor

例如，如果您将UIButton的全局色调颜色设置为blueColor，您可以在视图控制器中这样做，以覆盖tintColor。

myButton.tintColor = UIColor.blueColor()
